aiming point - at Astraeus we always brief the go-around before every approach and by this I mean that we concentrate as much ( or even more so ) on who says what, who presses what, who moves what, who does what, what GA thrust is required, etc, as we do on what the approach plate has to say about the latteral and vertical navigation aspects of the GA - and wherein, as you correctly say, it's something we don't often get to do for real and so careful review of the actuall stick and rudder bits go a long way towards helping to keep it safe.
Nb. This year alone I've presonally done two go-arounds, once due a GPWS "Terrrain pull-up" at Taba / HETB ( caused by an error in the approach procedure - since revised ) the other was as a result of not being able to see any approach lights at the MDA at Innsbruck / LOWI ( due snow storm ) - and I'm still here to type about it.
